The study, published in the scientific journal PLoS ONE, was carried out by a team of researchers led by Devon D. Brewer, director of the research firm Interdisciplinary Scientific Research. “Our findings are unexpected, because previous studies of youth indicated that arrest had no effect on, or even in creased, their delinquent and criminal behavior,” Brewer said.
The researchers analyzed police records of clients, or “johns”, arrested for prostitution in Colorado Springs, USA, and information on clients who sought HIV testing at the local health department or were involved in a large health department study of prostitutes and their sex partners. Arrested clients were usually caught in stings where female police officers posed as prostitutes in high-prostitution areas, and nearly all arrested clients were convicted. Clients first identified by arrest were similar to those first identified by the health department in terms of their demographic characteristics and prostitution activity. The researchers also examined records from several states in the USA and found that clients, after being arrested, did not appear to seek prostitutes in other communities or prostitutes who work in off-street settings.
These results suggest that simply arresting and prosecuting clients of prostitutes may be enough of a deterrent that additional interventions, such as sending clients to ‘john schools’ or educational programs that emphasize the harms of prostitution, may be unnecessary to lower recidivism,” Brewer noted. “However, because only a very small percentage of clients in a community are arrested, other strategies and increased enforcement may be necessary to reduce the demand for prostitution further.”

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
